Product details
Overview
TXS0104VRUTR from Texas Instruments is a 4-bit bidirectional voltage-level translator optimized for open-drain and push-pull logic interfaces, supporting 1.65V–3.6V on A port and 2.3V–5.5V on B port (VCCA ≤ VCCB), with 24Mbps push-pull data rate and integrated 10kΩ pullups per I/O - deployed in smartphone baseband-to-peripheral signal bridging.
For engineers reviewing the TXS0104VRUTR datasheet, TXS0104VRUTR pinout, TXS0104VRUTR application, or TXS0104VRUTR equivalent, key selection criteria include no-direction-control operation, OE-referenced-to-VCCA enable logic, thermal pad grounding requirement for RUT package, and compatibility with 1.8V/2.5V/3.3V/5V mixed-voltage SoC subsystems.
Technical Context
The TXS0104VRUTR uses pass-gate architecture with edge-rate-accelerating one-shot circuits to enhance low-to-high transitions, eliminating need for external pullups in open-drain applications. Each I/O includes internal 10kΩ pullup to its respective supply rail (VCCA or VCCB).
It operates without direction control or power-supply sequencing constraints: VCCA and VCCB may ramp in any order, though VCCA ≤ VCCB must be maintained during active operation. OE input is referenced solely to VCCA and places all I/Os in high-impedance state when low.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| A-port voltage range | 1.65V to 3.6V - supports 1.8V/2.5V/3.3V logic domains; must be ≤ VCCB |
| B-port voltage range | 2.3V to 5.5V - enables translation to 2.5V/3.3V/5V systems |
| Max data rate (push-pull) | 24Mbps - verified at VCCA = 2.5V, VCCB = 5V; defines real-time interface bandwidth |
| Max data rate (open-drain) | 2Mbps - applies across full VCCB range; sets I²C/SMBus-compatible timing ceiling |
| Propagation delay (A→B, push-pull) | ≤ 5ns - measured at VCCA = 1.8V, VCCB = 5V; ensures sub-10ns inter-subsystem latency |
| Output skew (same-direction) | 1ns - guarantees tight timing alignment across all 4 channels for synchronous buses |
| ESD rating (B port, HBM) | ±5000V - exceeds JEDEC JS-001 Class 3A; protects against handling-induced discharge in end-user devices |
Pinout & Package
TXS0104VRUTR uses a 12-pin UQFN (RUT) package measuring 2mm × 1.7mm with exposed thermal pad. The thermal pad must be soldered to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCA | A-port supply reference | Supplies A-side logic and OE input; sets VIH/VIL thresholds for A-port signals |
| VCCB | B-port supply reference | Supplies B-side logic and internal pullups; determines VOH/VOL for B-port outputs |
| GND | Ground reference | Common return path for both ports; required connection for thermal pad |
| OE | Output-enable control | Active-high enable referenced to VCCA; drives all I/Os into high-Z when low |
| A1–A4 | Bidirectional A-port I/Os | Each has 10kΩ internal pullup to VCCA; compatible with 1.65V–3.6V CMOS drivers |
| B1–B4 | Bidirectional B-port I/Os | Each has 10kΩ internal pullup to VCCB; tolerant of 2.3V–5.5V logic levels |
Key Features
| Feature | Design Value |
|---|---|
| No direction-control signal | Enables automatic bidirectional translation without MCU GPIO overhead or timing-critical control lines |
| Integrated 10kΩ pullups | Eliminates external resistors in open-drain designs (e.g., I²C), reducing BOM count and board area |
| Edge-rate acceleration | One-shot circuitry cuts rise time by >50% vs passive translators - critical for 24Mbps push-pull signaling |
| No power-supply sequencing | VCCA and VCCB may power up in any order; avoids complex PMIC coordination in multi-rail systems |
| High ESD robustness (B port) | ±5000V HBM withstand capability protects downstream 5V peripherals from system-level ESD events |

FAQ
What is the function of the thermal pad on the TXS0104VRUTR package?
The exposed thermal pad on the TXS0104VRUTR's 12-pin UQFN (RUT) package must be soldered to a PCB ground plane. This provides both thermal dissipation for sustained 24Mbps operation and electrical grounding for noise immunity and ESD current shunting. TI specifies this connection as mandatory - floating or unconnected thermal pads violate recommended layout and risk thermal shutdown or signal integrity degradation in TXS0104VRUTR applications.
Can TXS0104VRUTR translate between 1.8V and 5V logic without external components?
Yes. TXS0104VRUTR supports 1.8V on VCCA and 5V on VCCB with no external pullups or direction-control circuitry required. Its internal 10kΩ pullups on both ports and pass-gate architecture enable direct 1.8V↔5V bidirectional translation for open-drain (e.g., I²C) and push-pull (e.g., GPIO) signals - verified per datasheet Section 5.9 at 2Mbps (open-drain) and 23Mbps (push-pull) under those conditions.
How does OE pin behavior differ between TXS0104VRUTR and other level shifters?
The OE pin of TXS0104VRUTR is referenced exclusively to VCCA, not VCCB or an independent supply. This means OE must be driven by the A-port voltage domain. Pulling OE low disables all I/Os into high-impedance state within 250ns (tdis), and pulling OE high enables translation after 200ns (ten). This VCCA-referenced design simplifies control in systems where OE is managed by the lower-voltage processor side.
Is TXS0104VRUTR suitable for I²C bus translation?
Yes - TXS0104VRUTR is explicitly designed for open-drain applications like I²C. It meets 2Mbps maximum data rate requirements across its full VCCB range (2.3V–5.5V), includes integrated 10kΩ pullups eliminating external resistors, and maintains <1ns output skew across all four channels to preserve I²C timing margins. Its ±5000V HBM rating on the B port also enhances system-level ESD resilience for peripheral-facing I²C lines.
What happens if VCCA exceeds VCCB during normal operation of TXS0104VRUTR?
TXS0104VRUTR requires VCCA ≤ VCCB during active operation per datasheet Section 7.3.3. Violating this condition risks forward-biasing internal protection diodes, increasing ICCA/ICCB supply currents beyond specification (e.g., >15µA combined), degrading VOL/VOH accuracy, and potentially causing latch-up under sustained overvoltage. While power-up sequencing is flexible, runtime VCCA > VCCB is not supported and must be prevented by system-level voltage monitoring or regulator configuration.
